Analog Devices AD9857 Manuals

The CMOS 200 MSPS 14-Bit Quadrature Digital Upconverter AD9857 Rev. C is a high performance digital upconverter provided by Analog Devices, suitable for HFC data, telephony, and video modems, wireless base stations and other applications. The device features a 200 MHz internal clock rate, a 14-bit data path and excellent dynamic performance, providing 80 dB SFDR @ 65 MHz (±100 kHz) AOUT. The AD9857 also provides 4× to 20× programmable reference clock multipliers, reference clock multiplier PLL lock detect indicator, internal 32-bit quadrature DDS FSK capability, 8-bit output amplitude control, single-pin power-down function, four programmable, pin-selectable signal profiles, SIN(x)/x correction (inverse SINC function), simplified control interface, 10 MHz serial, 2-wire or 3-wire SPI®-compatible, 3.3 V single supply, single-ended or differential input reference clock and 80-lead LQFP surface-mount packaging.

The AD9857 is a 200 MHz 14-bit digital upconverter produced by Analog Devices. It has a 4× to 20× programmable reference clock multiplier, an internal 32-bit quadrature DDS, FSK function, 8-bit output amplitude control, a single pin power-down function, four programmable, pin-selectable signal profiles, SIN(x)/x correction (inverse SINC function), a simplified control interface, 10 MHz serial, 2-wire or 3-wire SPI compatible, 3.3 V single supply, single-ended or differential input reference clock, 80-lead LQFP surface-mount packaging, three modes of operation: quadrature modulator mode, single-tone mode, interpolating DAC mode, and is mainly used in HFC data, telephony and video modems, wireless base station, Agile, L-Band satellite communication and other applications.
